DomDocument - parser: Starting points

[bernard_hinault]

good evening dear PHPFreaks - hello to everybody.

i want to create a link parser. i have choosen to do it with Curl. I have some lines together now. Love to hear your review... Since i am new to programming i love to get some hints from experienced devs.

Here some details: well since we have several hundred of resultpages derived from this one: http://www.educa.ch/dyn/79362.asp?action=search

Note: i want to itterate over the resultpages - with a loop.

i take this loop:

for($i=1;$i<=$match[1];$i++)
{
  $url = "http://www.example.com/page?page={$i}";
  // access new sub-page, extract necessary data
}

what do you think? What about the Loop over the target-Urls?

BTW: you see - there will be some pages empty. Note - the empty pages should be thrown away. I do not want to store "empty" stuff.

well this is what i want to. And now i need to have a good parser-script.

Note: this is a tree-part-job:

1. fetching the sub-pages
2. parsing them
3. storing the data in a mysql-db

Well - the problem - some of the above mentioned pages are empty. so i need to find a solution to
leave them aside - unless i do not want to populate my mysql-db with too much infos..

Btw- parsing should be a part that can be done with DomDocument - What do you think? I need to combine the first part with tthe second - can you give me some starting points and hints to get this.

The fetching-job should be done with CuRL - and to process the data into a DomDocument-Parser-Job.
No Problem here: But how to do the DOM-Document-Job ...

i have installed FireBug into the FireFox...

now i have the Xpaths for the sites:
